Question

simplify (5/4x^2-3/2xy) (x+y+y^2); x=2 y= -2
​

Answer 1

Answer:

(5/4x^2-3/2xy) x=2 y= -2

Answer 2

Answer:-

We have

2x+y=5 ...(1)

3x−y=5 ...(2)

Adding equations (1) and (2),

⇒2x+y+3x−y=5+5

⇒5x=10

⇒x=2

Substitute the value of x in equation (1)

⇒y=5−2×2

⇒y=5−4

⇒y=1

∴ The value of x=2 and y=1
